CIGAR WRAPPING AND FINISHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 389,955, dated September 25, 1888.

Application filed March 19,1888. Serial No. 267,675.

To all whom. it may concern:

Be it known that I, CONRAD L. DRIEFER, a citizen of the United States, and a resident of the city of London,in the Province ofOntario, Canada, have invented certain new and useful Improvements in Cigar \Vrapping and Finishing Machines, of which the following is a specification.

The present invention relates to machines for wrapping and finishing cigars after they have been molded, eitherin an ordinary mold or by means of any suitable cigar-bunching machinesuch, for example, as that described in myapplication, Serial No. 249,130, filed September S, 1887, or that described in my ap plication filed contemporaneously herewith.

The object of my invention is to provide a device for wrapping and finishing cigars wherein any sized cigar may be wrapped with either a right orleft wrapper and wherein the tip of the cigar may be perfectly formed.

Myinvention consists in features of novelty which will be hereinafter fully described, and then particularly pointed out in the claims.

In the accompanying drawings, Figure I is a side elevation of my improved wrapping and finishing rollers and tip forming thimble. Fig. II is an end elevation of the tipforming thimble. Fig. III is alongitudinal section of one of the rollers. Fig. IV is a transverse section through the shafts on which the rollers are fixed, showing the frame in which they are mounted in elevation. Fig. V is an end elevation of the rollers. Fig. VI is a side elevation of a double set of rollers, with a tipforming thimble at each end to be used with right and left wrappers without reversing the device.

Referring now to the drawings, 46 represents a grooved pulley,around which may pass a belt driven from any suitable source,whereby the triangularlyanounted rollers 47, 4S, and 49 are revolved.

50 represcntsa frame,in which are mounted, in the lower ends of concentric slots 51, the shafts 52 and 53 ofthe upper rollers,48 and 49.

The shaft 54 of the lower roller, 47, is immovable transversely, butis revoluble in bearings on the frame 50. The outer end of shaft 54 carries pulley 46. The inner ends of the Shafts 52 and 53 carry,respcctively, pulleys 55 (No model.)

and 56, while their outer ends carry, respectively, pulleys 57 and 58. The inner end of shaft 54 carries pulley 54, while between the frame 50 and driving-pulley 46 it carries pulley 54". Around these pulleys pass elastic belts 59, which permit either of the upper rollers, 4S and 4.9,to be moved away from thelower roller to permit the insertion of a cigar between the rollers.

Pivoted near the top of frame 50 is a lever, 60, which may be swung back and forth by means of a cross-piece, 60, either end of which may be attached to a suitable device whereby it may be depressed. This lever extends down between the upper roller-shafts, 52 and 53,and has journaled in its lower end anti-friction rollers 61, adapted to bear upon and elevate either of the shafts of the upper rollers when either end of cross-piece 60 is depressed.

The construction of the rollers is as follows: Into screw-threaded sockets 61 in one end of each of the shafts are screwed the screwthreaded ends 62 of rods 63, having notches 64 at their other ends to admit of the use of a screw driver. The outer ends of the sockets 61 are enlarged and screw-threaded at 65 to permit of the insertion of screwthreaded tubes 66, fitting loosely on rods 63, said tubes being shorter than said rods. A portion of each of the shafts 52, 53, and 54 beyond the pulleys 54*, 55, and 56 is screwthreaded at 67, and beyond the screw-threads the shafts terminate in peripheral enlargements or flanges 68, over and behind which engage the ends of elastic tubes 69, (preferably made of rubber,) which are held in place and into engagement with said flanges by means of concave nuts 70, screw-threaded to engage the screw-threads 67 of the shafts.

On the outer ends of the rods 63 are sleeves 72, formed with flanges 73-and bearing against pins or projections 71 on the rods, so as to permit said rods to turn in the sleeves, while preventing relative longitudinal motion.

It will be seen that by screwing either in or out the rods 63 the elastic tubes 69, secured in any suitable manner to the sleeves 72 thereof,

correspondingly contract or stretch to make them more or less pliable, as occasion may require.

Rollers constructed as has been described IOC can be used in putting wrappers on cigarbunches of any size or shape, because the flexible sides will give to all different sizes. The bunches are preferably molded to the proper shape before being passed in between the rollers, whereas were the rollers made of metal or other hard or non impressible material there would have to be employed different sets of rollers for every different-shaped cigar.

I propose, instead of using a single set of rollers 47 48 49, to place a set upon each end of the rollcr-shafts, as shown in Fig. VI, thus having two sets, so that the reversal or shifting of the rollers from one side to the other of the frame is not necessary when right and left leaves are employed for wrappers. When a double set of rollers is used, a pulley, 46*, is placed upon the lower shaft, 54, of roller 47 between the ends of the frame 50, and a belt is run thereon. A tubular extension, 7 1-, of sleeve 72 of the lower roller, 47, has bearing in a journal provided in the bracket 75, for sup porting the outer end of said roller.

I will now proceed to describe the tip forming thimble.

76 is a vertically-adjustable slide arranged between checlopieces 77 of the bracket 75, and this slide is provided with vertical slots 78 79. Through slot 78 a set-serew, 80, passes and screws into the bracket 75, so that the slide may be secured at any desired height. Slot 7!) permits the passage therethrough of the end of rod 63 of lower roller, 47.

A horizontal extension, Si, of slide 76 is provided with u p wardly extending perforated lugs 82 83, between which is a spiral spring, 84-, fitting around stem 85 of thimble S6,which stem passes loosely througlrthe perforations in the lugs 82 83. This spring normally presses the thimble outwardly away from the rollers 4-7 48 419 by bearing upon the inner side of lug S3 and a collar, S7,which bears upon a pin, 87, inserted in an opening in the stem 85. On the outer end of the stem is screwed a knob or push-button, 88, whereby the thinr ble may be pushed forward when the wrapper which is placed upon a suitable table or support is about to be wound around the point or tip of the bunch, (the wrapper having been previously coated near the tip with paste,) so that a perfect tip, conforming to the shape of the thimble-cavity, is formed. The spiral spring will bring the thimble back to its former place when pressure on the push-button is relieved. By using such an adjustable thimble no friction on the bunch will take place before the wrapper is on it or before the thimble is applied, thereby not spoiling the end of the bu nch by the pressure of the thimble, and consequently a perfect point or tip can be made.

The lower end of the slide 76 is provided with side projecting pins 90, upon which bear downwardly-pressing flat springs 91 on each side of the slide. When the cigar enters the thimble, these springs allow the latter to come up to theright position to receive the tip of the cigar. \Vhen there is but one set of rollers employed, the thimble has to be turned halfway around when the rollers are reversed, so as to properly receive the point of the cigar. To provide for this turning of the thimble, and to prevent the same from turning around on its axis at the improper time, I secure nu derneath the bracket, at 92, a fiat spring, 93, having a projection, 94, on its free eud,which projection engages normally in either of the longitudinal grooves 95 on the stem 85 of the thimble. Vith the double set of rollers a tipforming thimble is applied at each end of the machine.
